Milliners mark out and cut patterns to create designs for hats. They then cut out the various components and assemble the hat. This may involve twisting, rolling, folding, reinforcing, sewing, steaming and pressing various components. Materials used include fabric, felt, fur, leather, straw, artificial flowers, ribbons, braids and feathers. They may also alter or renovate hats. They may also be involved in displaying hats or preparing them for sale.
